In certain uses of the invention, it will be desirable to retain thestringers or parts I G-I against accidental or pull apart separation,and to accomplish this, I provide the stops I5-I5' with grooves 3I-3I.AThese stops also have spring catch devices 32-32 having offset portions33-33 adapted to enter the grooves 3|- 3I respectively, to couple theparts IIJ-I against pull apart separation.

'I'he stops I5 I5 Yare united much the same as the slider halves. Inother words, they are divided by a common center line, as at 34, andeach part has a tongue or flange portion 35-35 arranged in a recessed orcutout portion of the companion part. For example, 35 fits in a recess36 of the part I5', whereas 35' fits in a recess 36 of the part I5, allas clearlyseen in Fig. V5 of the drawing.

In the position of the parts shown in Fig. l, the end stops have beeninterlocked, the slider halves assembled and the coupling of thestringers is effected inthe usual manner by endwise movement of theslider (downward in this instance) by means of Vpull 30.V

It will be recognized that as soon as the slider has been moveddownwardly to a point where the free ends of the scoops cross thelongitudinal center line of the slider, preparatory to intermeshing,theybegin to block the slider halves against separation, the axes ofpinsv 2121"; and when the scoops are Vactually intermeshed, lockingthemselves against transverse as well as pull apart separation in theusual manner, they provide a positive lock against the separation of theslider halves, and the slider functions just as if it were of the usualunitary construction.

To effect complete detachment of the member Ill-I it is merely necessaryto return the slider to the Fig. 1 position where the slider halves andthe end stops can be separated. Since the end stops are secured to theirrespective members Ill-I0 and the slider halves I G IG' are likewiserespectively coupled to such members by the encirclement of the beadsI3-I3 by the flanges 24-25 and 24-25', there are no loose parts such asare apt t0 get lost.

As illustrated in Fig.V 1 the last scoop of each Stringer is showncompletely outside of the slider channel but this is not essential. Itwill be recognized that, regardless of whether an interlocking type ofend stop is used, it is only necessary that the slider be movable tosuch a position relative to'the scoops that none of them crosses thecenter line of the slider to such an extent as to lock the slider halvesagainst separation. In other Words, one or two more scoops could'beadded to the stringers without interfering with the separation orassembly of the slider halves in the manner described.

that is, in the direction of` For purposes of description, each sliderpart may be said to comprise a channelled side and a thin walled side. Achannelled side being defined, for example, by the Walls I8-23,including the flanges of said walls, and the thin walled side by thewall I1.
